摘要 对一类基于递归细胞自动机的像素替换图像加密算法进行破解分析。对于不同密钥,我们根据迭代次数奇偶性的不同采用了不同的破解方法并选用了不同数量的明密文对。提出一种有效的选择明文攻击方法,获得该算法的所有密钥信息,Chen等人所提出的图像加密算法在选择明文攻击下不具有安全性。 Objective:To replace the image encryption algorithm for a class of cellular automata based on recursive pixel crack analysis. Methods:For different keys, we used a different method to break parity of different iterations and chose a different number next ciphertext pairs. Results:The proposed an effective method chosen plaintext attack. Conclusion:We have access to all the key information of the algorithm, the image encryption algorithm proposed by Chen et al in the chosen plaintext attack without having security.
